The land here rises roughly eight millimeters per year -- a rate that sounds negligible until you calculate that it produces one square kilometer of new territory annually. Islands that were open water a generation ago now break the surface. Peninsulas that were once separate islands have fused to the mainland. Boaters navigate cautiously, because skerries shoved upward by post-glacial rebound or shifted by winter sea ice can materialize where none existed the previous season.
